618/6-Z

The 618/6-Z deep groove ball bearing is a high-performance bearing specifically designed for precision miniature applications. Its core features focus on single-sided dust protection and high-precision stable operation. The ultra-compact specification enables easy adaptation to narrow installation spaces. It is made of 440C stainless steel or GCr15 high-carbon chromium bearing steel, which is wear-resistant, corrosion-resistant, and structurally strong. The factory pre-installs lithium-based lubricating grease to ensure smooth operation and eliminate the need for initial maintenance. The single-sided stamped dust cover can effectively prevent dust and impurities from entering to extend the service life. It also has a rated rotational speed of 65,000 r/min for grease lubrication and excellent dynamic and static load-bearing capacity. During high-speed operation, it is smooth without deviation. It is widely used in industries with strict requirements for protection, precision, and space, such as precision instruments, medical devices, consumer electronics, and micro motors. It is compatible with ISO standards and can be directly replaced with the same model of international brands. It is originally produced in China and has 118 pieces in stock. It supports 48-hour rapid shipping and offers two options: industrial packaging and commercial independent packaging.
